You are using manual voltage in BIOS? Having a constant 1.32 is quite toasty. I have my offset set to +0.1000 and my idle vcore is 1.088 @ 4.7GHz (1.392 in AIDA).

When you use manual voltage or auto, Idle voltage is higher than load voltage. Say if you set it to 1.32 using manual, then idle voltage is around 1.32 while load voltage is lower than that. Using offset gives you otherwise, idle voltage is lower than load voltage. While 1.32 at Idle may seems toasty, that's not really the case as when the CPU is idle it doesn't use much power. I tried using offset to get lower voltage at idle, but the temp wasn't much different from using manual 1.32 at idle.

Using offset is harder to get overall system stability than using manual. It's easy to test whether your system is stable under idle and under full load. But often is the in-betweens that screw things up. If you set voltage using manual, then you CPU get more voltage at 50% load than at 100% load. So if your system is stable under full load, it should be fine at those in-between values. But when you set voltage using offset, your CPU maybe getting insufficient voltage at, say, 50~60% load, even though it is stable under full load, that's becaues with offset, voltage increasings with CPU usage.

Ideally I want to use offset to set CPU voltage to get lowest possible voltage at different CPU load. But it's easier to start with manual settings to find out the various voltages needed at different loads. Then swtich to offset once you figure out how much voltage your CPU needs. This guys also experiment how LLC affect voltage differently when you use offset instead of manual:

Do you not have the ultra high setting? The one in between high and extreme? When I use ultra high, the voltage I set in BIOS is the same idle/load voltage I get.

I have that settings. I started with high, and then switched to extreme and skipped ultra high But then I was having problem with extreme settings, and I knew that high gave me stability, I went back to high, and skipped ultra high again. I guess it's fine for me since all I want to know is the actual cpu voltage under full load. I can just read that off from CPU-Z and ASUS Suite II. I just find it weird that using Extreme setting gave me this instability. Seems like setting LLC = Extreme is something to avoid. Heck, I'm only doing 4.5Ghz OC with a voltage lower than 1.35V. I'm not even talking about 5+Ghz OC with CPU voltage 1.4~1.5V some people are doing.
